Electrodeposition of Redox Polymers and Co-Electrodeposition of Enzymes by Coordinative Crosslinking This research was supported by the Welch Foundation and by the US Army Research Laboratory.

Abstract

When four conditions are met redox polymers can be electrodeposited by ligand exchange: the film must be electron- or hole-conducting; the redox centers of the deposited polymer that are based on transition metal complexes must contain a labile ligand in their inner coordination sphere; the redox polymer must contain a strongly coordinating but yet uncoordinated ligand; and the surface density of the adsorbed redox polymer must be high. By taking care of these points, the authors also succeeded in co-depositing enzymes and electroreducing/oxidizing their substrates with the electrodes obtained.
